Step 6: Clipping the cd case

Step 7: Yay...a hole in your ps2

Now that you have your window mod added, admire your handiwork...if you want to, add paint or other effects to your ps2, such as led's inside to light...

Step 5: Protecting your insides...

Now that you have a hole in your ps2 case, it's time to add a preotective covering, while still being able to see through the cutout.
Clear strong plastic works well, such as acrylic, but if you're like me, you don't just have a panel of acrylic just lying around for such a purpose. A good alternatve to this is a simple cd case. it's clear, strong enough for this purpose, as ther'll be no weight applied to it, and is thin enough to add without interfering with the insides of your ps2.
Another good alternative is an actual cd, with the label removed.
